Floppy disk is not a common hardware device of the computer, but a storage device. Floppy disks are the earliest removable backup storage devices among personal computer devices; reading and writing of floppy disks are completed through floppy disk drives. Floppy disk drives are designed to accept removable floppy disks. Currently, 3.5-inch floppy disks with a capacity of 1.4MB are commonly used.
Floppy Disk is the earliest removable media used in personal computers (PC). Reading and writing floppy disks is done through floppy disk drives. Floppy disk drives are designed to accept removable floppy disks. The most commonly used one today is the 3.5-inch floppy disk with a capacity of 1.44MB, which was once very popular. Later, due to the emergence of USB flash drives, the application of floppy disks gradually declined until they were eliminated.
Floppy disks are available in eight-inch, five-and-a-quarter-inch, and three-and-a-half-inch sizes, and are divided into hard magnetic areas and soft magnetic areas. Floppy disks are plastic sheets covered with magnetic coating that are used to store data files.
The storage format of a floppy disk: refers to how many concentric tracks each side of the disk is divided into, and how many sectors each track is divided into to store information. Sector is the basic storage unit of a floppy disk. Each read and write to the disk is performed in units of several sectors called "clusters".
Type
There are many kinds of computer floppy disks on the market, the commonly used ones are 5.25-inch and 3.5-inch, commonly known as 5-inch disk, 3-inch disk or large disk. Small cap. The symbols on the disc generally include DS, DD, HD, etc. DS means double-sided; D means low density; HD means high density. It should be noted that low-density floppy drives cannot read and write high-density floppy disks, while high-density floppy drives can read and write low-density floppy disks.
